New Member, Rough Idle after new timing belt

Featured Replies

I just bought a 89 Gl with a broken timing belt. Have it running but idles rough, and has a dead spot at 1800 RPM. I think I was off by one mark on the flywheel when I instaled the new belts. Would that make it run rough and hesitate?

If you have it off by teeth (usually on the cam), it'll run rough and have little power if any.

 

So yeah, recheck your timing belts.

Rechecked timing belts. looks ok. Checked the timing it was at 6°BTDC , I read a post that said SPFI should be20° BTDC. Changed the timing it now runs like a champ. This was not in the Subaru Manual under replacing timing belts. Lesson learned when replacing timing belts always check the timing when finished. :)

Makes sense. The disty is run by the driver's side cam. If you've had a timing belt with excessive slack in it, and someone set the timing like that, the second you put on a new tight timing belt, it throws your timing off.

dose any one know what the deg. btd is on an ea82 my idle is doing just that:slobber:

Look on the sticker under your hood. Else, its in your owners manual.

 

In general though, SPFI are 20btdc, and carb are 8btdc
